A worker notices a frayed extension cord but keeps using it because they’re in a rush to finish
a task.
That’s unsafe. Damaged cords can cause shocks or start fires. It should’ve been tagged
“Do Not Use” and replaced right away.
Someone is working on a ladder and decides to lean over to reach a tool just out of arm’s
length.
That’s a fall risk. You’re only supposed to move your body within the ladder rails. If it’s
out of reach, climb down and reposition.
You see a coworker not wearing their safety glasses while grinding metal.
That’s a PPE violation. Flying sparks or metal could injure their eyes. Safety glasses are
mandatory during grinding.
A team starts using scaffolding that hasn’t been inspected after it was moved.
Bad move. Scaffolds need to be inspected every time they’re reassembled or relocated.
It’s a safety requirement.

Someone walks through a site with earphones in.
That’s unsafe. You need to hear warnings or alarms. Earphones can block out important
sounds and distract you.
A new hire uses a power tool without being trained on it.
That breaks safety protocol. You should never use equipment without proper training—it
risks injury and damage.
During lifting, a worker bends at the waist with straight legs.
That’s bad technique. You should bend at the knees, keep your back straight, and lift with
your legs to avoid injury.
There’s a fire extinguisher on site, but it’s blocked by boxes.
That’s a code violation. Extinguishers must always be easy to see and reach in case of
emergency.
A forklift operator is using their phone while driving.
Completely unsafe. That’s distracted driving and can lead to crashes. Phones should
never be used when operating equipment.
A worker props open a machine guard for “just a minute” to speed things up.
Machine guards are there to prevent injuries. Removing or bypassing them, even briefly,
is a serious safety violation.
